Dr. Ben King

PhD - 2023


Ben's great passions in research and in life can be attributed to his unhealthy obsession with disc-shaped objects. In the lab, he spends his days (and occasional nights) evaporating silicon phthalocyanines into next generation transistors and sensors. In his spare time, Ben is either spinning his ever-expanding collection of records, launching frisbees into opposing teams' endzones on various local Ultimate teams, or rotating his bike wheels as he attempts to survive café rides with his speedy friends.
